This project is a Flappy Bird-style game built with React that integrates with the Solana blockchain to store high scores using an on-chain smart contract written in Rust and deployed with Anchor.

• React – JavaScript library for building UIs
• @solana/web3.js – Solana’s JS API for interacting with the blockchain
• @solana/wallet-adapter-react – React hooks and context for wallet connection
• @solana/wallet-adapter-wallets – Provides wallet implementations (Solflare, Phantom, etc.)
• @solana/wallet-adapter-react-ui – Prebuilt UI components for wallet connection
• @solana/wallet-adapter-solflare – Solflare wallet adapter
• @project-serum/anchor – Anchor TypeScript client for interacting with Solana smart contracts
• borsh – Binary serialization for Rust/JS interoperability
• buffer, process, stream-browserify – Polyfills for Node.js modules in browser
• ajv, ajv-keywords – JSON schema validation
• react-app-rewired – Customize Create React App config without ejecting

• Rust – Programming language for Solana smart contracts
• Cargo – Rust’s package manager
• Anchor – Framework for Solana smart contract development

Make sure you have Node.js and npm installed. In the project root, run:

npm install @solana/web3.js @solana/wallet-adapter-react @solana/wallet-adapter-wallets @solana/wallet-adapter-react-ui @solana/wallet-adapter-solflare borsh buffer
npm install @project-serum/anchor
npm install --save-dev @babel/plugin-proposal-private-property-in-object buffer process stream-browserify
npm install --save-dev react-app-rewired
npm install [email protected] [email protected] --save-dev --legacy-peer-deps

npm start

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Restart your terminal and verify:

rustc --version
cargo --version

(Optional) Update Rust:

rustup update

sh -c "$(curl -sSfL https://release.solana.com/v1.17.20/install)"

After installation, add Solana CLI to your PATH if needed. Then verify:

solana --version

cargo install --git https://github.com/coral-xyz/anchor avm --locked --force
avm install latest
avm use latest

Verify installation:

anchor --version

• Node.js (Already installed)
• Yarn (optional)

Build the Program:

anchor build

Test the Program:

anchor test

Deploy to Localnet:

solana-test-validator
anchor deploy

Deploy to Devnet:

solana config set --url devnet
anchor deploy

After deploying, copy your program IDL:

cp target/idl/flappy_sol.json frontend/src/idl.json

You can also build and deploy programs in-browser using:

• https://solanaplayground.com
• https://fiddle.shyft.to

These tools are great for testing and learning. For full projects, Anchor CLI is preferred.

1. Start Solana local validator (optional for local testing):

   solana-test-validator

2. Deploy your program locally:

   anchor build && anchor deploy

3. Start your frontend app:

   cd FlappySol
   npm start
